•convert the following:
•2.54 in to cm
•13.8 hr to s
•98.2 ft to m

6.4516  cm

49680 seconds

29.93136  m

Explanation:

2.54 in

We know that 1 inch= 2.54 cm, therefore, 2.54 in will be

2.54*2.54=6.4516  cm

13.8 h

We know that 1 hour=60 minutes

1 minute=60 seconds

Therefore, 1 hour=60*60=3600 seconds

13.8 hour=13.8*3600=49680 seconds

98.2 ft

We know that 1 ft=0.3048 m

98.2 ft will be equivalent to 98.2*0.3048=29.93136  m
